    • The present invention relates to a process for producing a 2-fluoro-6-halophenol as an intermediate; a process for producing a 2-alkoxy-3-fluorophenol and further a 1,2-dialkoxy-3-fluorobenzene from the 2-fluoro-6-halophenol; a second process for producing a 1,2-dialkoxy-3-fluorobenzene from the 2-fluoro-6-halophenol; and a 2-alkoxy-3-fluorophenol. The 2-fluoro-6-halophenol can be obtained using a 2-fluorophenol as a starting material and through a sulfonation reaction, a halogenation reaction, and a deprotection reaction. The 2-fluoro-6-halophenol is alkyl-etherified, and subsequently the halogen atom is converted into a hydroxyl group to obtain the 2-alkoxy-3-fluorophenol, which is further alkyl-etherified to thereby obtain the 1,2-dialkoxy-3-fluorobenzene. Alternatively, a 1,2-dialkoxy-3-fluorobenzene is also obtained by converting the halogen atom of the 2-fluoro-6-halophenol into a hydroxyl group to thereby form 3-fluorocatechol and subsequently alkyl-etherifying two hydroxyl groups thereof. The processes of the invention realize low production costs and high process yields, and thus are suitable for industrial production of a 1,2-dialkoxy-3-fluorobenzene.
    • 本发明涉及作为中间体的2-氟-6-卤代苯酚的制造方法。 从2-氟-6-卤苯酚制备2-烷氧基-3-氟苯酚和1,2-二烷氧基-3-氟苯的方法; 从2-氟-6-卤代苯酚制备1,2-二烷氧基-3-氟苯的第二种方法; 和2-烷氧基-3-氟苯酚。 2-氟-6-卤代苯酚可以使用2-氟苯酚作为原料,通过磺化反应,卤化反应和脱保护反应得到。 2-氟-6-卤代苯酚被烷基醚化,随后将卤素原子转化为羟基,得到2-烷氧基-3-氟苯酚,进一步进行烷基醚化,从而得到1,2-二烷氧基 -3-氟苯。 或者,也可以通过将2-氟-6-卤代苯酚的卤素原子转化为羟基,从而形成3-氟邻苯二酚,然后将其两个羟基烷基醚化,得到1,2-二烷氧基-3-氟苯。 本发明的方法实现了低生产成本和高工艺产率,因此适用于1,2-二烷氧基-3-氟苯的工业生产。

    • A low voltage electrical appliance having a mechanical interlock means comprises at least two contactors, wherein every contactor includes a base (11, 21), a support (12, 22), a top cover (4) and a contact holding sliding part (13, 23) in the base. Two contactors which are arranged in parallel both have one mechanical interlock means, which includes an interlocking element (3). The shaft of the interlocking element (3) may rotate in the slot of the base (11, 21). By the swinging of the interlocking element (3), a tang of the interlocking element (3) extends into the locking aperture of the contact holding sliding part, thereby preventing the energization action of the contact holding sliding part.
